Benefits of technology
The patent text describes an improved av device that can output video and audio signals while compensating for delays with high accuracy and reliability. The device can effectively compensate for delays even when the delay varies depending on the content being played, resolution, and device characteristics. The technical effect of this invention is improved accuracy and reliability in outputting video and audio signals while compensating for delay.
Problems solved by technology
In this case, the extent of the compensation for the delay depends on a user's subjective determination, and it is thus difficult to guarantee the accuracy and reliability of the compensation.
Also, such compensation is invariable, and it is difficult to apply the compensation to a case where the delay is varied depending on the types of contents to be reproduced, resolution, and characteristics of the devices.

Embodiment Construction
[0042]Below, exemplary embodiments will be described in detail. FIG. 1 illustrates an audio / video (AV) device according to an exemplary embodiment. The AV device 11 according to an exemplary embodiment may be achieved by a home theater system, an AV receiver, or the like device. The AV device 11 processes a video signal and an audio signal, and outputs the processed video signal to a display device 12 and the processed audio signal to a sound output device 13. The display device 12 may be, as a non-limiting example, a television (TV) or the like, and the sound output device 13 may, as a non-limiting example, by a loudspeaker system. The AV device 11 may receive the video signal and the audio signal from a source device 14. The source device 14 may be, as non-limiting examples, a digital versatile disc (DVD) player, a Blu-ray disc (BD) player, a personal computer (PC), a smart phone, a smart pad, a game console, etc. The source device 14 can transmit the video signal and the audio si...

An AV device including a first signal transmitter configured to output a video signal and a first audio signal corresponding to the video signal to a display device; a first signal receiver configured to receive a feedback signal of the first audio signal from the display device; a second signal transmitter configured to output a second audio signal corresponding to the video signal; and a controller configured to determine a processing delay time of the display device by comparing the first audio signal and the feedback signal, and control the second signal transmitter to delay the output of the second audio signal based on the determined processing delay time.
Description
CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from Korean Patent Application No. 10-2014-0001831, filed on Jan. 7, 2014 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field[0003]Apparatuses and methods consistent with exemplary embodiments relate to an audio / video (AV) device and a control method thereof, and more particularly, to an AV device, which outputs a video signal and an audio signal, and a control method thereof.[0004]2. Description of the Related Art[0005]An A / V device, such as a home theater system, an AV receiver, etc., receives a video signal and an audio signal from a source device, processes the received video and audio signals, and outputs the processed video signal to a display device and the audio signal to a sound output device. The display device receives and processes the output video signal and displays the process video signal as an image...
